Importance of moderation

“mitam bhuktva satam japtva
gatva satapadai sanai
vamabhaage sayaanasya
bhishak bhi kim prayojanam”

It translates roughly to mean that a person who eats moderately, chant 100 times (spend some time for meditation to be at peace with oneself), walk slowly about 100 steps (does physical activities moderately and consistently), and sleeps on left side will not need a doctor’s services
